Key legal question
Whether the criminal complaint against the cantonal order was admissible despite being directed only against the costs ruling in an intermediate decision.
Extracted holding
The appeal was inadmissible because the challenged order was an ordinary intermediate decision and caused no irreparable legal harm under Art. 93(1)(a) BGG.
Extracted reasoning
The practical purpose of the requested relief had already been achieved, and the costs decision could still be reviewed together with any final decision or, if necessary, separately later. Mere procedural delay or expense was insufficient.
